Perceptual Counter

  • Can count perceived items
  • May involve seeing, hearing or feeling items
  • May create perceptual replacements for abstract problems

Perceptual Counting

Here is one example of a perceptual counter.
 
When presented with 4 screened counters and 3 screened counters,  the child could not calculate how many there were altogether. However, when the counters were unscreened the child quickly counted them together. This child needs to see all the counters to solve the task.

Perceptual Counting (using perceptual replacements)

Here is another example of a perceptual counter.

When presented with 4 screened counters and 3 screened counters the child replaces the counters with fingers and successfully counts them together.

When presented with 8 screened counters and 5 screened counters the child attempts to replace the counters with fingers but runs out of fingers. 

When the counters were unscreened the child successfully counts them together.
